Printing Issues with Epson LQ-570e via licensed VMWare Workstation 12.5

We currently run Windows 10 workstations.  I have Windows 7 Pro 32-bit VMs running a legacy 32-bit version of R:Base.  We are migrating to True ERP but need to continue running R:Base as we are experiencing implementation problems.  The R:Base app prints to legacy dot-matrix Epson LQ-570e printers for multi-page forms.  I've been using a batch file using the Net Use command and it has been working fine.  But for some odd reason which I cannot diagnose, no one can print to their respective printers anymore.  The printers are attached directly to the users' workstation via centronix-to-usb adapter connection.
Sample text from a .bat file:
net use LPT1 /delete
net use LPT1 \\monica-vm\epsonlq
net use
pause
Thanks in advance for your help!

In VMware Workstation, in a guest machine, VM, Removable Devices:  Are you using a Removable Device in the guest machine that is needed in the host machine. Try unchecking USB removable devices and see if printing comes back.

Thank you John for your response.  There are legacy Brother LQ and Epson dot matrix printers attached via centronix to usb adapters to the host machines.  This organization uses a legacy version of R:Base 9.5 to run their company.  It is a 32-bit application and will not run on any 64-bit versions of Windows.  I created 32-bit Windows 7 VMs using VMWare Workstation 12.  The R:Base application runs on the VMs.  There are batch files containing the Net Use command that must be launched on the guest prior to launching the R:Base app.  The problem is that the R:Base app cannot print to the printers from within the VM.

I am not sure the Centronix to USB interface can communicate correctly through a Virtual Machine interface. I have had issues with like connections for radio dispatch configuration programs working in a VM. We had to revert to real machines.

a legacy version of R:Base 9.5 to run their company.  It is a 32-bit application and will not run on any 64-bit versions of Windows

Since all new machines will be Windows 10 (come another month) and the bulk of these will be 64-bit, it is probably time for the customer to upgrade their application.
